gnome is terrible comparing to macOS WM/DM. So many bugs and there is no way to tweak things like in mac. Please do me a favor and look about it before buying.
Not that I like GNOME, but that has to be the first time I've seen someone advocate macOS on the basis of customization. Could you say where you found macOS to let you tweak something that GNOME didn't? Is this including extra tools (GNOME Tweak Tool), or pure stock?
